Quick Answer
To order service kits for CAT machinery in Australia:
- Go through your Cat dealer or parts.cat.com — Hastings Deering (QLD, NT, PNG), WesTrac (WA, NSW, ACT) or William Adams (VIC, TAS).
- Order by serial number and interval — machine serial, engine serial, current SMU and whether it's PM1, PM2, PM3 or PM4.
- Order the PM kit, not loose filters — usually cheaper and it arrives complete with seals and O-rings.
- Add fluids and S·O·S bottles to the same order so the service isn't held up waiting on oil.
- Confirm stock location and freight — capital city to Bowen Basin or Pilbara is 1–3 business days.
- Log the PO and ETA against the machine in your maintenance system, not in someone's inbox.
Running several Cat machines? Price a Customer Value Agreement (CVA) so kits arrive ahead of each interval at agreed rates.
Why kit ordering is the service bottleneck
On most Australian mining and civil fleets, the service itself is the easy part. The hard part is having the right box of filters, seals and oil sitting in the store on the day the machine comes off the pad. A 336 excavator or a 777 truck that misses a 500-hour service because the wrong kit arrived is downtime you paid for twice — once in lost hours, once in freight.
Caterpillar has already done the hard work by packaging maintenance parts into interval-based kits. Ordering them properly is a repeatable workflow: serial, interval, kit, fluids, freight, then a record against the machine.
The kits you'll be ordering
Planned Maintenance (PM) kits
Cat packages PM kits by machine family and service interval — PM1 (250h/500h), PM2, PM3 and PM4. Each kit contains the filters, seals and O-rings for that interval, so nothing gets missed in the box.
Engine filter kits
Engine oil, primary and secondary fuel, water separator and crankcase breather elements for C-series engines (C7.1, C13, C15, C18, C27, C32, 3512). Cross-referenced to the engine serial, not just the machine.
Hydraulic & transmission kits
Hydraulic return, case drain, pilot, transmission and torque converter filters for 320/330/336 excavators, 966/980 loaders, D6/D8/D10 dozers and 773/777 trucks.
Air filter sets (primary & safety)
Outer primary plus inner safety element. Both are consumables — replace the safety element every 2–3 primary changes or immediately if the primary is damaged.
Fluids and sampling kits
Cat DEO-ULS engine oil, TDTO, HYDO Advanced and coolant in the same order as the kit, plus S·O·S oil sampling bottles so the service gets sampled properly.
Cat Reman & component kits
For component change-outs (pumps, final drives, turbos), Cat Reman kits carry gaskets, seals and hardware. Order these with the component, not after it lands.
Where to order Cat service kits in Australia
Caterpillar sells through territory dealers, so who you ring depends on where the machine is. Check current territories and contact details with Caterpillar Australia or your local branch before you set up accounts.
Your Cat dealer parts desk
Australia is split by dealer territory: Hastings Deering (QLD, NT, PNG), WesTrac (WA and NSW/ACT) and William Adams (VIC, TAS). Ring the branch parts desk closest to your site — Mackay, Emerald, Perth, Karratha, Newcastle, Melbourne — and ask for the PM kit by machine serial.
Parts.cat.com
Caterpillar's online parts store lets you add your machine by serial number, see the exact PM kit and parts list for that machine, check dealer stock and price, and order 24/7. Account customers see contract pricing and order history.
SIS2GO and the Cat app
SIS2GO and the Cat Central / Cat app show serial-specific parts diagrams and let you order kits from the phone in the workshop or ute. Handy when the fitter is standing at the machine and the office isn't.
CVAs and dealer service agreements
A Customer Value Agreement bundles PM kits, scheduled delivery and S·O·S sampling into one agreement, often with kits delivered ahead of each interval. Worth pricing against ad-hoc ordering if you run more than a handful of Cat machines.
What information to have ready
- Machine model AND serial number (e.g. Cat 336 GC, serial off the ID plate) — the serial decides the kit.
- Engine model and engine serial number — filters cross-reference to the engine.
- SMU (service meter hours) and the interval due: PM1, PM2, PM3 or PM4.
- Whether it's a scheduled service, a component change-out or a breakdown — this sets the urgency and freight.
- Fluids required with the kit — DEO-ULS, TDTO, HYDO Advanced, coolant — and quantities.
- Delivery address, site name, gate access and required-by date (Bowen Basin, Pilbara, Hunter Valley or metro).
- Whether you want genuine Cat, Cat Classic (older machines) or aftermarket cross-references.
- Account number, PO number and payment terms.
How to order — 5-step process
Confirm the machine, engine and hours
Take the model and serial off the ID plate and note the engine serial and current SMU. Two 336s a year apart can take different filters — the serial number is the source of truth.
Identify the interval, not just the parts
Work out whether the machine is due for PM1, PM2, PM3 or PM4. Cat kits are built around those intervals, so naming the interval gets you the right box first time instead of a list of loose part numbers.
Order the kit through parts.cat.com or the dealer
Add the machine by serial on parts.cat.com and the correct PM kit appears, or ring Hastings Deering, WesTrac or William Adams with the serial and interval. Add fluids and S·O·S bottles to the same order.
Check stock location and freight before you commit
Ask where the stock sits. A kit coming from Brisbane or Perth to a Bowen Basin or Pilbara site adds days and freight. Consolidate with other parts and book against a realistic service window.
Log the order against the machine and the job
Record PO, kit part number, price and ETA against the machine in your maintenance system — then mark the kit off when it lands in the store. Kits that go missing between order and fitment are the number-one reason services get pushed.
Best practices for kit ordering
Order kits, not loose part numbers
A PM kit is cheaper than the same filters bought individually and it arrives complete. Loose ordering is how the pilot filter or a single O-ring gets forgotten and the service stalls.
Keep one kit per machine on the shelf
A spare PM1 kit per machine is the cheapest insurance in the workshop. It costs a few hundred dollars and saves a day of downtime and a hot-shot freight bill.
Order by hours, not by calendar
Cat intervals are hour-based. Forecast kit demand off SMU and average hours per week so you don't end up with six kits for one machine and none for another.
Bundle fluids and S·O·S with the kit
Ordering oil, coolant and sampling bottles separately is how a service gets done without a sample taken. One order, one delivery, one line in the system.
Price a CVA if you run a fleet
Customer Value Agreements can deliver kits ahead of each interval at agreed pricing. Compare that against your current ad-hoc spend, including freight and downtime.
Watch counterfeit filters
Very cheap 'genuine Cat' filters from unauthorised sellers are often counterfeit. Buy through your Cat dealer, parts.cat.com or a reputable filter distributor — a $40 fake element can cost an engine.
Common mistakes that cost money
Ordering by model only
'A service kit for a 980' isn't enough. Build variants and engine changes mean different kits. Always order by machine serial and engine serial.
Missing the interval-specific extras
PM2 and PM3 kits add items PM1 doesn't (hydraulic, transmission, breather). Ordering a PM1 kit for a PM3 service leaves the fitter chasing parts mid-service.
Forgetting fluids and sampling bottles
The kit covers filters and seals, not oil. If DEO-ULS, TDTO, HYDO and coolant aren't on the same order, the machine sits waiting on drums.
Ordering the day before the service
Freight from a capital city to a remote site is 1–3 business days at best. Order to hours, hold spares, and log the ETA where the planner can see it.
Aftermarket without checking the spec or the site rules
Aftermarket cross-references are legitimate, but confirm micron rating, media, gasket and burst pressure — and check whether the site or engine warranty requires genuine Cat filtration.
Kits tracked in someone's inbox
If the only record of the order is an email on the parts controller's phone, nobody else can see what's coming, and the same kit gets ordered twice.
Know where every service kit is, before the machine comes in.
SprintSuite tracks parts orders, service kits and consumables against every machine and job — so scheduled services don't get pushed for a missing kit, and cost per hour is visible across the fleet.
